}
We made the main plugin a
PluginListener
and added a
cowList
variable and the
start of the
spawnCows()
function. Before we go any further, let's test
just that
much
—see if it builds without errors, and run the (empty)
spawnCows
function.
Small steps, remember. We don't have an event listener yet (in fact, we don't
even know
what
event we're going to listen for), so we'll use a trick.
We're going to add a command to
@Command
that's just for us—it's not for
users. But we can use it to test what we're doing as we go along.
So let's wire that up first, even before we've added any code to
spawnCows
:
@Command(aliases = {
"testspawncows"
},
description =
"Test cow spawning"
,
permissions = {
""
},
toolTip =
"/testspawncows"
)
public void
testSpawnCommand(MessageReceiver caller,
String[]
args) {
if
(caller
instanceof
Player) {
Player me = (Player)caller;
Location loc = me.getLocation();
spawnCows();
}
}
(We'll need to
importnet.canarymod.api.world.position.Location;
too.)
Now we have the ability to log in to the game and run the
/testSpawnCows
com-
mand to watch our cows spawn and make sure that works.
We don't actually spawn any cows yet, but let's just try it now and make sure
everything compiles, using
build.sh
, before we add any more code.
